Washing machine with agitator

ABSTRACT

A washing machine is presented. The washing machine is designed to open up the weave pattern that allows dirt to be removed. The washing machine comprises a cabinet having a back plate that separate the housing into a first chamber and second chamber. A drum is disposed within the first chamber and rotatably mounted to a first axle that extend through the back plate. Disposed within the drum is an agitator that is rotatably mounted to a second axle that also extends through the back plate. At least motor is connected to the first and second axle and in operation the drum and agitator rotate in opposite directions.

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No.61/871,918 filed Aug. 30, 2013.

BACKGROUND OF THE INVENTION

The present invention is directed to a washing machine and moreparticularly to a front load washing machine with an agitator.

Washing machines are well known in the art. While washing machinesexist, the most effective way to clean clothing remains hand washing.The reason is that the process of hand washing creates sufficientagitation of the fabric to open up the weave pattern that allows dirt tobe removed.

Attempts have been made to create agitation in the wash process toimprove the cleaning performance of the washing machines. Whileimproving the cleaning performance, these devices were complex and tooexpensive to manufacture. Therefore, a need exists in the art for awashing machine that addresses these deficiencies.

SUMMARY OF THE INVENTION

A washing machine is presented. The washing machine is designed to openup the weave pattern that allows dirt to be removed. The washing machinecomprises a cabinet having a back plate that separate the housing into afirst chamber and second chamber. A drum is disposed within the firstchamber and rotatably mounted to a first axle that extend through theback plate. Disposed within the drum is an agitator that is rotatablymounted to a second axle that also extends through the back plate. Atleast motor is connected to the first and second axle and in operationthe drum and agitator rotate in opposite directions.

DESCRIPTION OF THE DRAWINGS

The FIGURE is a side cut-away of a washing machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the FIGURE, a washing machine 10 has a top wall 12, abottom wall 14, side walls 16, a back wall 18, and a front wall 20 thatform a cabinet or housing 22. Hingedly mounted to the front wall 20 is adoor 24. Disposed within the cabinet 22 is a back plate 26 thatseparates the cabinet 22 into a first chamber 28, and a second chamber30.

Disposed within the first chamber 28 is a rotating drum 32 that ismounted to a first axle 34 that extends through an opening in the backplate 26. The drum 32 has a back wall 36, a side wall 38 and an openfront 40 that aligns with and is in communication with the door 24.Preferably, the drum 32 is angled downwardly from the open front 40toward the back wall 36 to cause clothing to fall toward the back wall36 of the drum 32.

Disposed within the drum 32 and rotatably mounted to a second axle 42that extends through an opening in the back plate 26 is an agitator 44.The agitator 44 is of any size and shape and preferably is not more thanhalf the length of the drum 32 and is conical in shape extending from abase 46 and tapering to a rounded nose 48. Mounted about the agitator 44is a helical screw fin 50. The agitator 44 rotates in a directionopposite of the rotation of the drum 32 and may also angle downwardlytoward the back plate 26. In one embodiment, a plurality of air jets 52connected to a source of pressurized air 54 are disposed on and aboutthe agitator 44. The use of the agitator 44 in conjunction with the drum32 leads to improved cleaning performance and a more gentle wash cyclethat opens up the weave portion of clothing fabrics.

Disposed within the second chamber 30 is at least one and possibly twomotors 56. The motor 56 is operatively connected to the first and secondaxles 34 and 42 through the use of a gear train 58 or plurality ofpulleys 60 and belts 62. Also, extending into the second chamber 30through an opening in the back wall 18 is an inlet tube 64 and an outlettube 65 that are in fluid communication with the first chamber 28.

In an additional embodiment, an electrical transducer 66 is used inassociation with the drum 32 and/or agitator 44 to provide very fastvibration, either linear or elliptical oscillation to the devices. Thetransducer 66 is mounted directly to the drum 32 and/or agitator 44 orto the first and/or second axle 34 and 42.

In yet another embodiment, the vibrations created by the agitator 44associated with the transducer 64 are ultrasound. Alternatively, thevibrations can produce micro-currents, which are emitted within theradio frequency spectrum. Micro-currents of this nature give off thermalenergy as well as assist in enriching oxygen, which in turn increasesthe ability to remove stains and brighten clothing. In one arrangement,the mode of vibration be selectively set to produce linear oscillation,elliptical oscillation, ultrasound, or micro-currents.

From the above discussion, it will be appreciate that the smalldetachable golf bag assembly presented improves upon the state of theart. It will be appreciated by those skilled in the art that othervarious modifications could be made to the device without parting fromthe spirit and scope of this invention. All such modifications andchanges fall within the scope of the claims that are intended to becovered thereby.
